Effect of preoperative YAG laser anterior capsulotomy on the incidence of posterior capsule opacification: ten year follow-up.

One hundred twenty-two patients, who were followed for ten years, had bilateral extracapsular cataract surgery with implantation of J-looped posterior chamber lenses between 1980 and 1981. On the first eye an anterior capsulotomy was performed with a pico-second YAG laser 12 to 20 hours before surgery; on the second eye a capsulotomy was performed manually at the time of surgery. Four of the eyes (3.27%) with laser capsulotomies had opacified posterior capsules after ten years; 61 of the eyes (50.00%) with manual capsulotomies had opacified capsules that had to be opened with a YAG laser.

[Hypoplasia of the optic nerve head].

Optic nerve hypoplasia is not a rare eventuality in children. This report discusses the clinical features of 10 new cases on a multiple point of view including optic canal tomography, fluorescein angiography and cat's examination. Optic nerve hypoplasia is not always accompanied by decreased visual acuity: sector fields are often identified in these cases.

[Two cases of chondrodysplasia punctuate are reported].

The first one was a 13 months old lewish boy with typical features of the rhizometic type; clinicaly the patient demonstrated cataract, esotropia, nystagmus, malnutrition, micromelia, contracture, multiple stippled calcifications about the periphery of the cartilagenous structures of the vertebral bodies, sternum, wrists, knees, heels, ribs; and profound mental retardation, After cataract operation, the head of the optic nerve demonstrate to be narrower than usualy and white. Pathologic studies of the lens' fragments after surgery showed the cataract to be without any specific characters. The child now 2 yrs and 1/2 old is still alive but in poor condition. The second was a 16 months old Arabic boy without typical features but with a cataract and stippled calfications of a limited number of epiphysae. Pathologic studies of the lens after cataract surgery showed the cataracts to be without any specific characters, the optic nerves were normal. The child now 3 yrs old is normally developed and in good conditions. It is remarquable to note that in both cases there was an history of consanguinity (mother and father were first cousins).
